Abstract: The A* algorithm is a graph search algorithm which has shown good results in terms of computational complexity for Maximum Likelihood (ML) decoding of tailbiting convolutional codes. The ...

In this paper, we propose an efficient and fine-grained image encryption algorithm, named EFIE. The main step of EFIE is the proposed permutation-substitution synchronization procedure, which is much ...

This project implements the Playfair Cipher in Java, a classical encryption algorithm that secures text using a 5x5 matrix generated from a keyword. It provides functionality to encrypt a message, ...
